Romantic hikes and secret sexual trysts were mentioned in the diary of Stephanie Birkitt, the pretty intern at the center of the scandal which ignited after iconic talk show host David Letterman admitted to “having sex with women who work for me” during a tension-filled confession on his show last week.

Birkitt’s diary, according to the New York Post, details the ins and outs of her infidelities with the talk show host, even while she lived with her CBS producer boyfriend — and the man Letterman has accused of plotting to extort him — Robert Halderman.

According to the diary, Letterman, 62, extended Birkitt, a graduate of Benjamin Cardozo Law School, a generous offer to work as his personal attorney. Birkitt wrote in the diary that she was actually trying to persuade the man she was cheating on, Halderman, to have children with her, based on the financial stability they would enjoy if she was a lawyer on Letterman’s payroll.

Letterman would make weekly drives to visit Birkitt at the Connecticut home she and Halderman shared for the past five years, according to the diary. Birkitt kept Halderman’s suspicions in check by reassuring him Dave was just a “friend” who shared “a platonic relationship” with her.

The diary serves as a key prop in the funnyman’s bizarre saga, as an enraged Halderman only found out Birkitt was two-timing him with the gap-tooth funnyman when he leafed through its pages last December.
